Yesterday at WWDC10 Steve Jobs announced the iPhone 4. Apple claims this is the biggest leap forward since the original iPhone was released in 2007. The iPhone 4 features an all new design, Apple A4 processor, Retina display, 5-megapixel camera, and much more. Current iPhone users are probably wondering should I get the new iPhone 4? Well read on as we go over the new iPhone 4 and tell you if you should get one or not.

iPhone 4 Hardware Overview The iPhone 4 is not just new hardware inside of the same iPhone design. This new design all starts with glass. iPhone 4 is situated between two glossy panels of aluminosilicate glass — the same type of glass used in the windshields of helicopters and high-speed trains. Chemically strengthened to be 20 times stiffer and 30 times harder than plastic, the glass is ultradurable and more scratch resistant than ever. It’s also recyclable.

You will also notice the steel around the edges of the iPhone 4. Created from Apple’s own alloy, then forged to be five times stronger than standard steel, the CNC-machined band is the mounting point for all the components of iPhone 4. The band provides impressive structural rigidity and allows for its incredibly thin, refined design. It also functions as both iPhone 4 antennas. This new design is incredibly 24% thinner than the iPhone 3GS coming in at 9.3mm thick and weighing 4.8 ounces. Making it the thinnest smartphone ever!

Now onto the display, the 960-by-640 backlit LCD display boasts a pixel density of 326 pixels per inch, making it the highest-resolution phone screen ever. To achieve this, Apple engineers developed pixels so small — a mere 78 micrometers across — that the human eye can’t distinguish individual pixels. That makes text remarkably sharp and graphics incredibly vivid. IPS technology also provides excellent color and contrast from almost any viewing angle. Apple has also updated the camera on the iPhone 4. This 5-megapixel camera is capable of shooting HD video and taking great photos. They finally added a LED flash too!

Powering all of this is Apple’s A4 processor; yes the same one that is in the iPad. This processor as Apple claims can process more data while consuming less battery than before.
